江苏省不同季节蔬菜农药残留状况调查分析

Investigation and analysis of pesticide residues in vegetables at different seasons in Jiangsu province

目的调查分析近3年江苏省内主要蔬菜生产县(区)不同季节蔬菜农药残留状况。方法按照GB 2763-2016《食品安全国家标准食品中农药最大残留限量》对蔬菜中农药残留进行检测并对检测结果进行判定。结果第一季度的蔬菜农药残留检出率和超标率是全年4个季度最高的;叶菜类蔬菜农药残留风险是各类蔬菜中较大的且各年度间变异小;限用农药残留风险比非禁限用农药大,非禁止限用农药中腐霉利、啶虫脒残留风险较大。结论江苏省不同季节蔬菜农药残留存在一定风险,有必要在今后工作中进行原因排查和分析,以便于在发现的风险关键点加强农产品安全监测。

Objective To investigate and analyze the pesticide residues in vegetables at different seasons in main vegetable producing counties(districts)of Jiangsu province in recent 3 years.Methods According to GB 2763-2016 National food safety national standards for maximum residues of pesticides in foods,pesticide residues in vegetables were detected and the test results were determined.Results The detection rate and excess rate of vegetable pesticide residues in the first quarter were the highest in the 4 quarter.The risk of pesticide residues in leafy vegetables was larger among all types of vegetables and had less variation between years.The risk of restricted pesticide residues was greater than that of non-restricted pesticide residues,and there was a greater risk of residues of procymidone and acetamiprid in pesticides that were not prohibited.Conclusion There are certain risks of pesticide residues in vegetables in different seasons in Jiangsu province.It is necessary to investigate and analyze the causes in future work in order to strengthen the safety monitoring of agricultural products at the key points of the risks found.
